| titleOfInvention | Manufacturing method of high strength reduced iron for blast furnace |
| abstract | The present invention relates to a method for producing high strength reduced iron for blast furnaces.n n n The present invention provides a central portion having a carbon and iron ratio of 0.2 to 0.25 and a diameter of 8 to 10 mm, and a surface layer portion having a carbon and iron ratio of 0.16 to 0.2, based on the percent by weight, on the outer surface of the central portion. Provided are a method for producing carbonaceous-containing pellets having a diameter of 12.5 to 13.2 mm, and a method for producing reduced iron for blast furnace using the same.n n n According to the present invention, by varying the weight ratio of carbon and iron according to the central portion and the surface layer portion, there is an effect of providing a method for producing blast furnace reduced iron having high strength and reduction rate. |
